DBus API for process monitoring and task managing applications

[stsdc]

Problem

The lack of an API and portals for accessing info of processes and managing them, makes it meaningless to distribute applications with process monitoring and managing functionality as Flatpaks.

Proposal

As @danirabbit suggested, I'm opening this issue to initiate work on DBus API for process monitoring applications. Such API should allow to:

• List all processes of host
• Read stats of processes /proc/%d/stat
• Manage a selected process (send signals to end, kill, etc. a process)

With a such API it becomes possible to introduce sophisticated portals for a specific, yet still important type of tools. (e.g. Monitor).
